The invention relates to the technical field of vehicle control, and particularly discloses a vehicle energy-saving auxiliary control method and device, a vehicle and a storage medium. The method comprises the steps that a target lane where a vehicle is located in real time and target object information corresponding to the target lane are obtained, the target object information comprises front traffic light information and obstacle information, and the relative speed, the relative distance and the safe vehicle following distance between the target vehicle and a front target object are calculated according to the target object information; the real-time scenes comprise a scene without energy-saving assistance, an energy-saving assistance scene with obstacles and traffic lights and an energy-saving assistance scene only with traffic lights, three control strategies are provided for the three different real-time scenes, the comfort of the vehicle is improved, the energy consumption of the vehicle is reduced, meanwhile, energy recovery is automatically carried out, and the energy utilization rate of the vehicle is improved. Multiple energy conversion times of driving and power generation recovery are reduced, the efficiency loss of an electric driving system and the energy loss of a mechanical braking system are effectively reduced, and rear-end collision accidents are reduced.

    本申请涉及车辆控制技术领域,具体公开了一种车辆节能辅助控制方法、装置、车辆及存储介质。方法包括通过获取车辆实时所在的目标车道,以及目标车道对应的目标物信息,目标物信息包括前方红绿灯信息及障碍物信息,根据目标物信息计算目标车辆与前方目标物的相对速度,相对距离以及安全跟车距离,判断车辆应进入哪种实时场景,实时场景包括无节能辅助场景、有障碍物及红绿灯的节能辅助场景及仅有红绿灯的节能辅助场景,针对三种不同的实时场景提供三种控制策略,提高车辆舒适性及降低车辆能耗,同时自动进行能量回收,减少驱动与发电回收的多次能量转换次数,有效降低电驱动系统的效率损失和机械制动系统的能量损失,并且减少追尾事故发生。
